BT905 BT-800 Cordless Phone Rechargeable Battery Compatible with Uniden BT-905
Quick take
This QBLPOWER cordless phone battery replacement is designed for Uniden handsets that use a 3.6V, 600mAh Ni-Cd battery pack (sold as a 2-pack). It is a practical option for reviving older landline-style cordless phones when the original batteries have degraded, but you need to confirm the exact original battery part number and connector match.
Pros and cons
Pros
- Rechargeable 3.6V, 600mAh Ni-Cd battery format intended for compatible Uniden models
- Includes 2 batteries, useful if you have more than one handset
- Buyer feedback commonly describes it as working as expected and fitting properly
- Compatibility list includes the original-style part numbers such as BT-1006 and BT-905
Cons
- Compatibility depends on matching the original battery part number and connector, not just the phone model name
- Ni-Cd chemistry is older, so performance and charging behavior can differ from newer battery types in other cordless systems
What buyers think
Buyer-review evidence for this battery pack is limited but generally positive. The recurring themes are straightforward: it installs correctly, it powers the cordless phone as intended, and it is described as matching expectations. A few notes also emphasize the value of keeping working landline phones instead of replacing the whole handset or base unit, since dead batteries are a common failure point. That said, detailed feedback on runtime, long-term battery health, or charge-cycle consistency is not robust enough to establish a precise performance pattern.
Who this battery is for
Choose the BT905 BT-800 (BT-905) replacement if you have a compatible Uniden cordless handset and you are trying to restore normal operation after the original battery pack no longer holds a charge. This pack is specifically positioned for phones that use a 3.6V Ni-Cd battery with about 600mAh capacity, in an AA*3 battery configuration.
Key specs to confirm before you buy
- Voltage: 3.6V
- Capacity: 600mAh
- Chemistry: Ni-Cd (nickel-cadmium)
- Pack size: 2 batteries
- Form factor: AA*3 battery configuration
- Fit and compatibility: match the original battery part number (examples listed include BT-1006, BT-905, BT-800, and related part numbers) and the connector type
Compatibility is everything for cordless batteries
With replacement handset batteries, the biggest buying risk is ordering the right phone model but the wrong battery pack. This battery emphasizes matching the original battery part number and ensuring the size and connector fit. If you can identify the battery label on the existing pack, that is the most reliable way to confirm you are getting the correct replacement.
Pros and cons in real buying terms
Reasons it makes sense
- If you run multiple handsets, a 2-pack is convenient and can reduce the odds of needing another order soon.
- For cordless systems that require the specific 3.6V Ni-Cd format, this is aligned to that requirement rather than being a generic “any battery” replacement.
What to watch for
- If your existing battery uses a different voltage, chemistry, or connector style, this may not be the correct swap. Double-check the original part number before purchasing.
- Because the chemistry is Ni-Cd, shoppers who are trying to match a newer system’s battery behavior (different charging expectations) may need to consider battery-type compatibility across the whole cordless setup.
Verdict
The BT905 BT-800 compatible battery pack is a solid, practical choice for buyers with Uniden cordless phones that use a 3.6V, 600mAh Ni-Cd handset battery and want to bring dead batteries back into service. The main caveat is careful compatibility confirmation (part number and connector), since that determines whether the batteries will actually fit and function properly.

FAQ
How do I check if this battery is compatible with my Uniden phone?
Match your current handset battery’s part number and confirm the connector and physical fit. This pack is intended for Uniden models and original-style battery numbers such as BT-905/BT-800/BT-1006 family replacements, but the safest approach is to compare the label on your existing battery.
What are the key specifications (voltage and capacity)?
This replacement battery pack is rated at 3.6V and 600mAh, using Ni-Cd chemistry, and it is sold as a 2-pack in an AA*3 configuration.
Will it fit if my phone model number looks similar?
Possibly, but you should not rely on the phone model alone. Cordless handsets can use different battery packs with different connectors, and compatibility is best verified by matching the original battery part number and connector.
Is this battery rechargeable?
Yes. It is a rechargeable Ni-Cd battery designed for use in compatible cordless handset charging systems.
Why buy replacement batteries instead of a new cordless phone?
If the base station and handset hardware still work, replacing worn handset batteries can restore normal calling without replacing the entire system. This is especially appealing for older landline-style cordless phones where the main issue is battery degradation.
